알코올 및 사염화탄소에 의해 유발된 급만성 간손상에 대한 지구자 열수추출물의 보호효과 = Hepatoprotective Effects of Hovenia dulcis Extract on Acute and Chronic Liver Injuries induced by Alcohol and Carbon Tetrachloride

다국어 초록 (Multilingual Abstract)

Objectives : The purpose of this study was to evaluate the hepatoprotective effect of Hovenia dulcis extract on acute and chronic liver injuries induced by alcohol and CCl4 in mice and rats. Methods : In acute alcohol-induced liver injury, mice were administered Hovenia dulcis extracts (60 and 200 mg/kg) orally before and after alcohol administration. In chronic alcohol-induced liver injury, mice were administered alcohol containing liquid diet for 4 weeks. The mice were administered H. dulcis extracts (60 and 200 mg/kg) mixed with the liquid diet. In acute CCl4-induced liver injury, rats received a single dose of CCl4 (2 mL/kg in olive oil, intraperitoneally). Rats were administered H. dulcis extracts (30, 100 and 300 mg/kg) before and after CCl4 administrations. After the ends of the administrations, the serum levels of AST and ALT were measured using chemical analyzer, and γ-GTP levels were measured using spectrophotometer. Results : In acute alcohol-induced liver injury, H. dulcis extracts treated group showed significant reduction in ALT levels compared to those of control group. In chronic alcohol-induced liver injury, it inhibited weight-loss compared to normal group and showed significant reduction in AST, ALT and γ-GTP levels compared to control group. In acute CCl4-induced liver injury, it also showed significant reduction in AST, ALT levels compared to control group. Conclusions : The results show that H. dulcis extract has hepatoprotective effect in acute and chronic alcohol-induced liver injury and acute CCl4-induced liver injury. These findings suggest that H. dulcis could be a potent hepatoprotective agent.
